Abstract
The invention discloses a pesticide bactericide composition for preventing and treating diseases such as powdery mildew of cucumber, anthracnose of mango and the like and application thereof. According to the application, the cloroxen and the amino-oligosaccharin are compounded to generate a synergistic effect, so that the formed pesticide bactericide has a good sterilization effect and has good activity on diseases such as cucumber powdery mildew and mango anthracnose; the bactericidal composition has the advantages of different action mechanisms of the effective components in the bactericidal composition, increased action sites, expanded control spectrum, reduced single selection pressure on pathogenic bacteria, favorable delay of the generation speed of the drug resistance of diseases, low dosage, low cost, low side effect, no influence on the safety, yield and the like of crops, and the like.
Description
Technical Field
The invention relates to the technical field of pesticides, in particular to a pesticide bactericide containing cloroxen and amino-oligosaccharin for preventing and treating diseases such as cucumber powdery mildew and mango anthracnose and application thereof.
Background
Cucumber powdery mildew is one of the main diseases in the current cucumber production. The cucumber powdery mildew is commonly called as 'white hair disease', the damage of leaves is the heaviest, then, the leaves and stems are the second, after the leaves and tender stems are infected by the powdery mildew, the symptoms are similar to those on the leaves, the scab is smaller, and the powder is less. Yellow spots begin to appear on the leaves, then the yellow spots expand and develop into round or oval spots, and white powdery mildew layers appear on the surfaces. Typically, there are more lower blades than upper blades, and more blades on the back than on the front. The mildew stains are independently dispersed at the early stage and then combined into a large mildew spot, even the large mildew spot can cover the whole leaves, the photosynthesis is seriously influenced, the normal metabolism is interfered, the premature senility is caused, and the cucumber yield is lost; mango is one of the most important tropical fruits and widely planted in tropical and subtropical regions, china is the second largest mango producing area in the world, and the mango anthracnose (Colletotrichum Corda) fungus is a type of globally distributed phytopathogen, the caused mango anthracnose is one of the most main diseases on mango, latent infection is formed on immature mango, and huge economic loss is caused by the attack of the mango during storage and transportation after picking; at present, powdery mildew of cucumber and anthracnose of mango are mainly prevented and controlled by chemical agents, but pesticide residues are easily caused by using a large amount of chemical agents, harm is caused to human health, and meanwhile, the drug resistance is easily generated by applying a single chemical pesticide for a long time.
In view of the severity of diseases such as powdery mildew of cucumber, colletotrichum gloeosporioides and the like and the harmfulness of chemical pesticides, the invention provides a method for preventing and treating diseases by utilizing amino-oligosaccharins and chlorofluoroethanoxazole in a compound combination, which has the advantages of different action mechanisms, increased action sites, expanded control spectrum, reduced single selection pressure on pathogenic bacteria, contribution to avoiding the generation of disease resistance and delaying the generation speed of disease resistance, low dosage, low cost, low side effect of the bactericidal composition, no influence on the safety, yield and the like of crops and the like.
Chlorofloxacin (mefentrifluconazole) is the first triazole bactericide containing an isopropanol structure and has the chemical name of (2 RS) -2- [4- (4-chlorophenoxy) -alpha, alpha-trifluoro-o-tolyl]-1- (1H-1,2,4-triazol-1-yl) propan-2-ol with CAS number 1417782-03-6 and molecular formula C 18 H 15 ClF 3 N 3 O 2 The relative molecular mass is 397.8, and the molecular structural formula of the chlorofluoromethane is shown as formula 1. The chlorofluoromethane can be dissolved in water and an organic solvent, the solubility of the chlorofluoromethane in water is 0.81mg/L at the temperature of 20 ℃, the water solubility is lower, the volatility is lower, and the chlorofluoromethane cannot enter underground water through leaching; the solubilities in the organic solvents acetone, ethyl acetate, xylene and 1,2-dichloroethane were 93.2, 116.2, 8.5 and 55.3mg/L, respectively. Chlorofloxacin has a melting point of 126 deg.C and a degradation point of 300 deg.C, and decomposes under boiling conditions, but is not flammable.
The chlorofluoromethane is a novel isopropyl alcohol triazole bactericide which has broad spectrum, high efficiency and systemic effect and has the functions of eradicating and protecting, and belongs to sterol demethylation inhibitors. Different from the widely used triazole bactericide, the chlorofluoroether oxazole contains an isopropanol structure, so that the mutation of pathogenic bacteria can be reduced, and the drug resistance of the pathogenic bacteria can be delayed.
Amino-oligosaccharin, english name: oligosaccharins are low-toxicity bactericides extracted by microorganism metabolism and have an anti-disease effect, and amino-oligosaccharins can inhibit the growth of some pathogenic bacteria, influence fungal spore germination, induce hypha morphological variation, spore biochemical change and the like. Can excite the gene in the plant body, produce chitinase, glucanase, preservative, PR protein and the like with disease-resistant function, has the function of activating cells, is beneficial to the recovery of the damaged plant, promotes the roots and the seedlings, enhances the stress resistance of crops, and promotes the growth and the development of the plants. The amino-oligosaccharin solution can be widely used for preventing and treating diseases caused by viruses, bacteria and fungi of fruit trees, vegetables, underground rhizomes, tobacco, traditional Chinese medicinal materials and grain and cotton crops.
Because the control difficulty of cucumber powdery mildew and mango anthracnose is high, the harm is serious, the control medicaments commonly used at present, such as prochloraz and the like, are old medicaments with long time and high resistance, and the control effect is poor. In the published reports, the activities of the chlorofluoromethane and the amino-oligosaccharin on cucumber powdery mildew and mango anthracnose are not deeply researched, and the compounding of the chlorofluoromethane and the amino-oligosaccharin is not reported at present. Therefore, in the prior art, different medicaments are combined to control diseases, but the effect of the combination of different medicaments is uncertain, and the combination of different medicaments can produce synergistic effect and antagonistic effect. And the effect of combinations of different agents on different diseases is also uncertain.
Disclosure of Invention
In order to solve the technical problems in the background technology, the application provides a pesticide bactericide containing chlorofluoromethane and amino-oligosaccharin for preventing and treating diseases such as cucumber powdery mildew, mango anthracnose and the like.
